I'm working on a music player (I'm a beginner), I've gotten the basics down but I've been stuck on something for the last few days.
I'm wanting to have a listbox that (only) music files can be dragged onto, once they are dragged onto it I want the listbox to add it as an item on that listbox. So basically, I'm wondering how to drag items onto listboxes, restrict that to only music files (specifically .wav & .mp3) and have that dragged item be added to the listbox.
PS. I'm making this media player myself, without WMP or DirectSound (I believe it's called).
I need to run my program as admin because it accesses the registry on load. Well I wanted to implement a drag and drop feature but have come to find there is a access issue with running as admin and the dragenter event. Is there any known workarounds for this? I have searched all over the place.Just a side note I only need to get the file location from the item being dragged in...
View 3 RepliesI'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?

View 5 RepliesI have a class with a Property called 'Value' which is of type Object.Value can be of any type, a structure, a class, an array, IList etc.My problem is with the setter and determining whether the value has changed or not.This is simple enough for value types, but reference types and lists present a problem.For a class, would you assume that the Equals method has been implemented correctly, or just assume that the value has changed every time the setter is called?If I did assume it's changed, then perhaps I should assume it for value types as well, so that the behaviour is consistent.
View 2 RepliesI have created a list form that gets attached to a main form in VB.NET. This all works fine except that when the main form gets activated, I need the list to be brought to the front as well. I have put in a simple IF function to do this but when I added these lines of code, the main form, as well as the list form now do not get brought to the front until you let go of the mouse button. Obviously this means that if you drag the form, it stays at the back until you let go of the mouse button.
The code that I added is below:
If CRL.Visible = True Then
CRL.BringToFront()
End If
CRL is the list form.
If I comment out this code again, the main form get brought to the front while dragging but obviously the list form does not. The main form as well as the list form are MDI children.
I am creating a text editor in Visual Basic .Net 2005. I want to get the list of filenames dragged into the MDI form. I can't figure out the proper code to do that.
View 2 RepliesI�m having trouble with the picturbox control, my problem in its basic form is:I have a picture Box array consisting of 9 picture boxes each with a different image in loaded at run time these are names 0.jpg to 8.jpg I then have 2 more picture Boxes named ansOne and ansTwo. I have made it so you can drag the images of these numbers to either of these picture Boxes It this next part I�m having trouble with:
I then want to have thoughs images represent a sum so when a button is clicked it adds or multiplies thoughs images together but as numbers ("badly put I know ")I am very unshore of where to start. After the image has been dragged how would I know what image has been dragged and turn that in to its integer equilivent?I had thought of using split string or something similar to just get the number before the .jpg so tried picAnsOne.imageLocation but that throghs a null reference And that�s as far as I have got.

View 1 RepliesI want to achieve the following:
The user drags text from any open window not related to my application ( like firefox or word, for example) onto button1 on form1 in my application. when he/she does that, a new form (called form2 that contains a richtextbox) will open and the dragged text is directly copied (or inserted) into the richtextbox of the new form. button1 has allowdrop set to true. Beyond that I don't know how to proceed.
I tried:
e.effects = DragDropEffects.Copy
But it seems it is not enough.
I have gotten my application to open with an associated file type, but now I'm trying to figure out how to associate the file types to the app. I associated them on my PC manually by right clicking on a file and selecting "Open With.." and check-marking "Always use this application to open this file type".What I want to do, is have my program make itself the default application for a file type with the press of a button.If it makes it easier, I'm writing a text editor and want to give the users the option of making it the default text editor for .txt &/or .rtf files.
